My daughter 6 years old is having an allergic dry cough for almost a month. the cough has reduced with homeopathic medicines, but since today morning she is continuously sneezing (probably has sneezed more than 30 times since morning). there is watery discharge from her nose and she is complaining of itching near her nose. is this also due to allergy? how long will allergies last and when will they completely disappear with homeopathy? please answer, as I am worried about one issue after another cropping up. Is this a sign of low immunity?
